COVID-19 vaccine trial led by Oxford University has only a 50% chance of success as what, the professor co-leading the development of the vaccine told media. Adrian Hill, director of Oxford's Jenner Institute, which has teamed up with drugmaker AstraZeneca Plc to develop the vaccine, said that an upcoming trial, involving 10,000 volunteers, threatened to return no result due to low transmission of Covid-19 in the community.
